An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-41393 in the wild and no public exploit code.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2021-41393/ (Markdown: https://insights.sbomify.com/CVE-2021-41393/index.md)","id":"CVE-2021-41393","markdown":"https://insights.sbomify.com/CVE-2021-41393/index.md","name":"CVE-2021-41393","record":{"aliases":["GHSA-vx7m-hm5r-82w3"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Teleport SSH access","requires_auth":"none","summary":"Attackers can forge SSH host certificates in Teleport, bypassing security controls and potentially impersonating trusted hosts.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"teleport","vendor":"goteleport"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"Teleport before 4.4.11, 5.x before 5.2.4, 6.x before 6.2.12, and 7.x before 7.1.1 allows forgery of SSH host certificates in some situations.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Security feature bypass in n/a","id":"CVE-2021-41393","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2021"},"n_packages":0,"n_references":4,"next":{"headline":"Supply chain in n/a","id":"CVE-2021-41394"},"packages":[],"prev":{"headline":"Command injection in n/a","id":"CVE-2021-41392"},"products":["n/a"],"published":"2021-09-18","related":[{"cvss_score":8.8,"headline":"Improper token validation leading to code execution in Teleport","id":"CVE-2022-36633","kev_date_added":null,"published":"2022-08-24"},{"cvss_score":6.5,"headline":"Information disclosure in n/a","id":"CVE-2022-38599","kev_date_added":null,"published":"2022-12-08"},{"cvss_score":6.5,"headline":"Other in n/a","id":"CVE-2021-41395","kev_date_added":null,"published":"2021-09-18"},{"cvss_score":5.3,"headline":"Supply chain in n/a","id":"CVE-2021-41394","kev_date_added":null,"published":"2021-09-18"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can forge SSH host certificates in Teleport, bypassing security controls and potentially impersonating trusted hosts.","url":"https://insights.sbomify.com/CVE-2021-41393/"}
